As the detector signature of each resonant decay is similar to that of its corresponding non-resonant decay, systematic uncertainties that would otherwise dominate the calculation of these efficiencies are suppressed. The efficiency of the non-resonant B + → K + e + e − decay therefore needs to be known only relative to that of the resonant B + → J/ ψ( → e + e −) K + decay, rather than relative to the B + → K + μ + μ − decay. In this equation, each branching fraction can be replaced by the corresponding event yield divided by the appropriate overall detection efficiency ( Methods), as all other factors needed to determine each branching fraction individually cancel out. 2, 65), the R K ratio is determined via the double ratio of branching fractions Since the J/ ψ → ℓ + ℓ − branching fractions are known to respect lepton universality to within 0.4% (refs. To help overcome the challenge of modelling precisely the different electron and muon reconstruction efficiencies, the branching fractions of B + → K + ℓ + ℓ − decays are measured relative to those of B + → J/ ψ K + decays 64. Updated QED and electroweak contributions are presented, together with new. In the remainder of this paper, the notation B + → K + ℓ + ℓ − is used to denote only decays with 1.1 < q 2 < 6.0 GeV 2 c −4, which are referred to as non-resonant, whereas B + → J/ ψ( → ℓ + ℓ −) K + decays are denoted resonant. This paper reviews and updates the Standard Model prediction of the lepton g-2. The B + hadron contains a beauty antiquark, \(\overline\) resonances, such as the ϕ(1020) meson. Measurable quantities can be predicted precisely in the decays of a charged beauty hadron, B +, into a charged kaon, K +, and two charged leptons, ℓ + ℓ −. One method to search for new physics is to compare measurements of the properties of hadron decays, where hadrons are bound states of quarks, with their SM predictions. Particle physicists have therefore been searching for ‘new physics’, that is, new particles and interactions that can explain the SM’s shortcomings. The SM is unable to explain cosmological observations of the dominance of matter over antimatter, the apparent dark matter content of the Universe, or the patterns seen in the interaction strengths of the particles. However, it is clear that the model is incomplete. When the compressed JPEG needs to also be a JPEG, there is mozjpg to explore as well.The standard model (SM) of particle physics provides precise predictions for the properties and interactions of fundamental particles, which have been confirmed by numerous experiments since the inception of the model in the 1960s.

Thanks to the VPX authors for their highly tuned bool reader and bool writer implementations. Many thanks to Matthias Stirner and HTW Aalen University for the development of the uncmpJPG library. ![]() It easier to step through the code without other threads hitting breakpoints. If the bug happens in single threaded mode, also you can pass -singlethread which makes This will stop verification and let you debug the app as a single process application. To avoid setting follow fork flags, please pass -skipverify to the command line. The standard forks that let it do a secure verification in a separate process. Lepton is designed to be easy to debug, but a command line requirement is necessary to prevent Then create a new pull request through the github interface Debugging I'm granting you a license to distribute said code under the terms of this agreement. The code I'm contributing is mine, and I have the right to license it. This can be used to archive large photo collections, or to serve images live and save 22% bandwidth. Lepton is a tool and file format for losslessly compressing JPEGs by an average of 22%. If you would like to continue using Lepton, please check out Microsoft’s implementation of Lepton in Rust or alternatively consider switching to other lossless compression methods such as Brotli or to modern image formats such as WebP or JPEG XL. We apologize for any inconvenience and appreciate your understanding. Therefore, after some consideration, we’ve decided to deprecate and archive the project. While we did ensure that the reported vulnerabilities don’t affect our internal use of Lepton, we unfortunately don’t have the capacity to properly fix these and future issues in this public repo. ![]() This includes providing timely fixes to bugs and vulnerabilities such as those that were recently reported to us. Thank you so much for using and contributing to Lepton over the years! We’ve recently realized that we no longer have sufficient resources to adequately support this project. ⚠️ Deprecation Notice for the Dropbox Lepton project
